Ultra-Low-Power, Wide-Bandwidth Haptic Driver

The DA7283 ultra-low power haptic driver, combines custom drive sequences, on- and off-resonance, at up to 1kHz. The DA7283 drives both ERM and LRA (narrow and wideband) actuators and track resonance up to 300Hz producing highly complex click/vibration touch effects in a wide range of applications.

The DA7283 differs from the DA7280 and DA7281 as it is hardware controlled and is ideal for applications that require a simple buzz or click. It also provides the capability to go into a full standby mode, lowering current consumption to 5nA.
